Everyone knows: full of expectation, you put fresh watercress on the windowsill, but after a few days an unsightly layer appears – mold! This not only causes frustration, but also raises questions about how hygienic home growing really is. But the good news: with the right method this problem is a thing of the past! Watercress is an integral part of a healthy diet in November and generally in the winter months and is often no longer fresh in the supermarket, which is why it is worth growing it yourself.
Because conventional methods often fail
Many people still use home remedies such as cotton wool or kitchen paper to grow watercress. What is often not considered is that these materials store water poorly, which leads to waterlogging or dryness. Both promote the formation of mold and watercress falls into oblivion. Additionally, any chemicals or bleaching agents contained may dissolve and pass into the watercress. Cultivation with cotton wool or Kitchen roll it is not optimal for many reasons. We will explain to you a 100% natural method that offers optimal conditions to the watercress.

The mold-free solution: the right growing tray with natural fiber fleece
Very often it is the wrong one seed tray responsible for the frustration. We know it ourselves. Half our basement is full of grow trays that just don’t work. That’s why we developed our own growing bowl, which is handcrafted from high-quality ceramic and can solve several problems at once.
- Optimal ventilation: The well thought-out structure ensures that the seeds receive enough air, mold has no chance.
- Even humidity: Thanks to the special grooves on the bottom of the seed tray, the seeds remain perfectly moist without being too wet.
- sustainability: No plastic, no wadding, but a high quality natural fiber fleece made with hemp fibers, therefore only natural materials perfect for Mini vegetables like watercress they are suitable.
The right seeds must be fresh
Fresh seeds seem trivial. But above all watercress seeds are very sensitive. Their optimal germination time is shorter than other seeds and the problem with large production for supermarkets is that they have to be bottled in huge quantities and then stored for many months or years until they end up in the supermarket and finally to the customer. So you buy seeds that have probably been sitting there for two years or more and germinate poorly in the seed tray. We wanted to change this because in recent decades we have often experienced frustration when newly purchased watercress seeds only partially germinated. That’s why we found a small seed company that bottles high quality organic seeds for us that don’t have a long shelf life and I can promise you that the germination rate will blow your mind. Our organic watercress seeds are so fresh that you will see that they germinate much better than the watercress seeds you previously purchased. So try it and see for yourself. Here you will find our high quality Organic Watercress Seeds (order here).
Because supermarket watercress doesn’t offer true freshness
Already grown up watercress from the supermarket may seem practical at first glance, but it has already lost much of its freshness and nutrients. Due to long transport and storage routes, vegetables quickly lose the vital substances that make them so valuable. Furthermore, watercress from supermarkets is often sold in plastic packaging, which is neither sustainable nor optimal in terms of taste.

Even common methods like this watercress strainer or that Kresseigel they are not ideal. Both systems do not provide a constant supply of moisture and can dry out the roots. There is also often a lack of ventilation, which encourages mold growth. If you really want to enjoy fresh, frustration-free watercress, you should rely on well-studied cultivation systems that create optimal conditions – like this one Sprouts love the seed tray.

- Daily care: Spray once a day with the plant sprayer and observe how the watercress grows. From the second or third day you can remove the wooden cover because then the seeds need light and now you can see the little seedlings growing bigger every day – fresh and mold-free!
